Abstract
Thrombosis of retinal veins is one of the most common retinal vascular diseases that may lead to vascular blindness. The latest epidemiological data leave no illusions that the burden on the healthcare system, as impacted by patients with this diagnosis, will increase worldwide. This obliges scientists to search for new therapeutic and diagnostic options. In the 21st century, there has been tremendous progress in retinal imaging techniques, which has facilitated a better understanding of the mechanisms related to the development of retinal vein occlusion (RVO) and its complications, and consequently has enabled the introduction of new treatment methods. Moreover, artificial intelligence (AI) is likely to assist in selecting the best treatment option for patients in the near future. The aim of this comprehensive review is to re-evaluate the old but still relevant data on the RVO and confront them with new studies. The paper will provide a detailed overview of diagnosis, current treatment, prevention, and future therapeutic possibilities regarding RVO, as well as clarifying the mechanism of macular edema in this disease entity.

Abstract
PURPOSE To characterize hemi-retinal vein occlusion (HRVO) in patients presenting to a multi-tier ophthalmology hospital network. METHODS This retrospective, hospital-based study analyzed 2,834,616 new patients between August 2010 and June 2021. Patients with a clinical diagnosis of HRVO in at least one eye were included as cases. Data were collected using an electronic medical record system. Data were compared to the findings noted in branch RVO (BRVO) and central RVO (CRVO) patients. RESULTS HRVO constituted 0.9% ( n = 191) of all the retinal vein occlusions (RVOs), with the mean age being 60.55 ± 10.14 years. Most patients were male (125, 65.45%) with unilateral (92.67%) affliction. Majority presented during the sixth (31.41%) or seventh (32.46%) decade of life. Most patients reported mild (37.07%) or moderate (27.32%) visual impairment, with vision < 20/200 being less common in HRVO (25.8%) and BRVO (17.2%) compared to CRVO (44.1%) ( P < 0.00001). Glaucoma was diagnosed and treated in 49 (23.90%) eyes, which was much higher than CRVO (11.45%) and BRVO (5.04%) ( P < 0.001), though neovascular glaucoma was much less than CRVO (2.9% vs. 9.2%) ( P = 0.0037). On follow-up, HRVO eyes (12.2%) had lesser vision loss compared to CRVO eyes (13.7%) (this difference does not look very significant to me), though BRVO had the least (9.1%) vision loss. CONCLUSION HRVO is a rare RVO, presenting more in males. It causes less-severe visual impairment compared to CRVO. Large majority of patients with HRVO do not have identifiable systemic risk factors other than age. Preexisting glaucoma was more associated with HRVO compared to other RVOs.

Ophthalmol Ther 2024; 13:1255-1269. [PMID: 38498277 DOI: 10.1007/s40123-024-00915-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Accepted: 02/19/2024] [Indexed: 03/20/2024] Open
Abstract
INTRODUCTION This systematic review and meta-analysis aimed to provide an updated evidence base for clinical decision-making by comparing the efficacy and safety of aflibercept 2 mg and ranibizumab in treating retinal vein occlusion (RVO). METHODS A systematic search was conducted using eight databases up to December 2021. Randomized controlled trials (RCTs) and real-world studies (RWSs) comparing aflibercept and ranibizumab in patients with RVO were evaluated. The primary outcomes assessed were efficacy, number of injections administered, and adverse events. RESULTS Three RCTs (424 patients) and 11 RWSs (1415 patients) were included. For central RVO (CRVO), RCTs demonstrated a comparable efficacy, whereas RWSs showed that mean changes from baseline in best-corrected visual acuity (BCVA) and central retinal thickness (CRT) were significantly greater with aflibercept compared to ranibizumab; the number of injections of aflibercept was fewer than that of ranibizumab in RCTs, but similar in RWSs. For branch RVO (BRVO), no statistically significant difference in efficacy between the two drugs in RCTs/RWSs was observed, with fewer injections of aflibercept at 12 months in RWSs. The safety profiles of both drugs were similar for both CRVO and BRVO. CONCLUSIONS For CRVO, aflibercept had similar efficacy and safety profile but with fewer injections versus ranibizumab in RCTs; RWSs showed greater BCVA improvement and CRT reduction with aflibercept than ranibizumab. For BRVO, RCTs showed similar in efficacy, safety, and injection numbers for both drugs, while RWSs demonstrated that aflibercept required fewer injections at 12 months of follow-up. Overall, this study provides updated evidence for clinical decision-making in the treatment of RVO.

Graefes Arch Clin Exp Ophthalmol 2023; 261:3569-3579. [PMID: 37432451 PMCID: PMC10667145 DOI: 10.1007/s00417-023-06163-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2023] [Revised: 06/13/2023] [Accepted: 06/28/2023] [Indexed: 07/12/2023] Open
Abstract
PURPOSE For the treatment of macular edema, in addition to the use of antivascular endothelial growth factors, steroids are also used intravitreally and sub-Tenon. Side effects include among others cataract formation and elevation of intraocular pressure (IOP). The aim of this retrospective study was to elicit the IOP elevation after administration of various steroidal medication, the time of onset, and the efficacy of the administered IOP-lowering therapies. METHODS We included 428 eyes with a postoperative (n = 136), diabetic (n = 148), uveitic macular edema (n = 61), and macular edema after retinal vein occlusion (n = 83). These patients were treated with one or more diverse steroidal agents once or multiple times. These drugs included: triamcinolone acetonide (TMC) as intravitreal injection (TMC IVI) or sub-Tenon (TMC ST), as well as dexamethasone (DXM) and fluocinolone acetonide (FA) intravitreally. An increase of IOP of ≥ 25 mmHg was designated as pathological. A steroid response in anamnesis, the time of onset of IOP rise from the first administration, and the therapy administered were documented. RESULTS Of 428 eyes, 168 eyes (39.3%) had IOP elevation up to a mean of 29.7 (SD ± 5.6) mmHg, which occurred at a median of 5.5 months. Steroids most frequently leading to rise of IOP included DXM (39.1% of all eyes receiving that drug), TMC IVI (47.6%), TMC ST combined with DXM (51.5%), DXM with FA (56.8%), and TMC IVI with DXM (57.4%). A Kaplan-Meier analysis and the Log Rank test showed a significant difference (p < 0.001). IOP rise was treated as follows: 119 conservatively (70.8%), and 21 surgically (12.5%, cyclophotocoagulation 8.3%, filtering surgery 1.8%, in 4 the steroidal drug implant was removed 2.4%), and 28 eyes received no therapy (16.7%). Sufficient IOP regulation was achieved in 82 eyes (68.9%) with topical therapy. In 37 eyes (31.1%) with persistently elevated intraocular pressure, topical therapy had to be continued over the follow-up of 20 ± 7 months. CONCLUSIONS IOP increases after any type of steroid application are not rare. Results of our study let us suspect that especially therapy with intravitreal dexamethasone, either as a monotherapy or in combination with another steroid, tends to increase IOP more than other steroids. Regular IOP checks are necessary after each steroid administration, with possible initiation of long-term conservative and/or surgical therapy if necessary.

Abstract
PURPOSE We aim to contribute to the literature in terms of treatment safety with our real world data by examining the anterior segment complications and follow-up results of patients who underwent dexamethasone implants in our clinic. METHODS The records of patients treated with at least one intravitreal dexamethasone implant for various retinal diseases: diabetic macular edema (265 eyes), central retinal vein occlusion (45 eyes), retinal vein branch occlusion (91 eyes), postoperative cystoid macular edema (18 eyes), non-infectious uveitis (37 eyes) and other (14 eyes) between July 2013 and April 2020 were reviewed. RESULTS After 925 injections were applied to 470 eyes of a total of 383 patients, the eyes were controlled during a mean follow-up of 24 months. No complications were detected in 328 eyes. Intraocular pressure (IOP) above 25 mmHg was detected in 97 eyes (20.6%) that had no previous history of ocular hypertension. Of these 97 eyes, 71 (73.1%) eyes with increased IOP were treated with topical monotherapy, 26 (26.8%) eyes were treated with topical combined therapy and 1 (1.03%) patient had glaucoma surgery. Cataracts requiring surgical intervention developed in 55 (%21.73) of 253 phakic eyes. Three patients have anterior chamber dislocation of dexamethasone, 1 patient was hospitalized with sterile endophthalmitis on the 7th day after the injection, and pars plana vitrectomy was performed. CONCLUSION This study is the first long-term follow-up study in our country evaluating the safety of dexamethasone implant injections in various retinal diseases and presenting the first real world data. Cataract progression and increased IOP were found to be the most common side effects. We observed that the patient's diagnosis did not cause a statistically significant change in the observation of side effects. As a result of our findings, close follow-up of IOP after the injection of dexamethasone implants would be appropriate.

Abstract
PURPOSE To investigate whether a nonlinear association between central subfield thickness (CST) on spectral-domain OCT and concurrent visual acuity letter score (VALS) exists in eyes treated initially with aflibercept or bevacizumab for macular edema associated with central retinal vein occlusion (CRVO) or hemiretinal vein occlusion (HRVO) in the Study of Comparative Treatments for Retinal Vein Occlusion 2 (SCORE2). DESIGN Long-term follow-up after a randomized clinical trial from 64 centers in the United States. PARTICIPANTS Participants were followed up to 60 months and treated at investigator discretion after completing the 12-month treatment protocol. METHODS Two-segment linear regression models were compared with simple linear regression models of VALS on CST. Pearson correlation coefficients were calculated to assess strength of CST and VALS associations. MAIN OUTCOME MEASURES Central subfield thickness was measured by OCT and VALS by the electronic Early Treatment Diabetic Retinopathy Study methodology. RESULTS Estimated inflection points, reflecting turning points at which the CST and VALS association changes from positive to negative, calculated at 7 postbaseline visits, range from 217 to 256 μm. A strongly positive correlation exists to the left of each estimated inflection point, ranging from 0.29 (P < 0.01 at month 60) to 0.50 (P < 0.01 at month 12), and a strongly negative correlation exists to the right of each estimated inflection point, ranging from -0.43 (P < 0.01 at month 1) to -0.74 (P < 0.01 at month 24). Randomization statistical tests showed that 2-segment models are favored over 1-segment models for all postbaseline months (P < 0.001 for all tests performed). CONCLUSIONS The relationship between CST and VALS in eyes with CRVO or HRVO after treatment with anti-vascular endothelial growth factor (VEGF) therapy is not simply linear. The usually modest correlations between OCT-measured CST and visual acuity belie strong left and right correlations present in 2-segment models. Post-treatment CST close to the estimated inflection points showed the best expected VALS. The SCORE2 participants with a post-treatment CST after treatment close to the estimated inflection points of 217 to 256 μm showed the best VALS. In patients treated with anti-VEGF for macular edema associated with CRVO or HRVO, a thinner retina is not always associated with better VALS.

Abstract
BACKGROUND This study intended to illustrate a rare case of pyogenic granuloma (PG) in retinal vein occlusion (RVO) patient after dexamethasone (DEX) implant therapy. CASE DESCRIPTION A 58-year-old female who underwent DEX implant therapy a month ago due to RVO presented with a mass in her right eye. Anterior segment analysis revealed a slowly enlarging, round, fleshy vascular mass indicating PG located at the injection site. Although surgical excision was planned, because of the Covid-19 pandemic, a patient could not come for surgery. Ocular examination revealed a spontaneous PG disappearance three months later. A small mass could, however, be detected using an anterior segment optical coherence tomography. CONCLUSION While superficial PG regression can only be observed by slit-lamp biomicroscopy, extensive root ingrowth can be clearly differentiated by anterior segment optical coherence tomography. Besides, depending on the nature, size, location, and associated symptoms, some PG may be left to regress but with close monitoring.

Abstract
BACKGROUND The comparative safety and efficacy of different doses of intravitreal triamcinolone acetonide (IVTA) for diabetic macular edema (DME) and macular edema (ME) secondary to retinal vein occlusion (RVO) is unclear. OBJECTIVES This meta-analysis aimed to compare the safety and efficacy of different doses of IVTA in this setting. METHODS A systematic literature search for randomized clinical trials (RCTs) was conducted on Cochrane Library, Ovid MEDLINE, and EMBASE from January 2005 to May 2022. Studies that reported on patients with DME or ME secondary to RVO that received treatment with different doses of IVTA were included. A random-effects meta-analysis was performed. Cochrane's Risk of Bias Tool 2 was used to assess the risk of bias, and Grading of Recommendations, Assessment, Development and Evaluation (GRADE) guidelines were used to assess certainty of evidence. RESULTS Five RCTs reporting on 1,041 eyes at baseline were included in this meta-analysis. In eyes with ME secondary to RVO, high-dose (4 mg) IVTA achieved a significantly better change in best-corrected visual acuity (WMD = -4.75 ETDRS letters, 95% CI = [-7.73, -1.78], p = 0.002) and reduction in retinal thickness (WMD = -93.02 μm, 95% CI = [-153.23, -32.82], p = 0.002) at months 4-6 compared to low-dose (1-2 mg) IVTA. However, high-dose IVTA had a higher risk of intraocular pressure-related adverse events (RR = 2.99, 95% CI = [1.05, 8.50], p = 0.04) and cataract surgery (RR = 5.67, 95% CI = [3.09, 10.41], p < 0.00001) than low-dose IVTA in eyes with ME secondary to RVO. These efficacy and safety differences in high-dose and low-dose IVTA were not observed in DME eyes. CONCLUSIONS The RCT evidence in this setting is limited. High-dose IVTA achieved greater improvements in visual acuity and reductions in retinal thickness than low-dose IVTA at months 4-6. However, high-dose IVTA had a less favorable safety profile than low-dose IVTA. The significance of these outcomes was based on patients with ME secondary to RVO, but not DME.

Abstract
Background Eyes sustaining open globe trauma are at high risk of severe visual impairment. Proliferative vitreoretinopathy is the most common cause of retinal detachment and visual loss in eyes with open globe trauma. There is evidence from experimental studies and pilot clinical trials that the use of adjunctive steroid medication triamcinolone acetonide can reduce the incidence of proliferative vitreoretinopathy and improve outcomes of surgery for open globe trauma. Objective The Adjunctive Steroid Combination in Ocular Trauma or ASCOT study aimed to investigate the clinical effectiveness of adjunctive triamcinolone acetonide given at the time of vitreoretinal surgery for open globe trauma. Design A phase 3 multicentre double-masked randomised controlled trial randomising patients undergoing vitrectomy following open globe trauma to either adjunctive triamcinolone acetonide or standard care. Setting Hospital vitreoretinal surgical services dealing with open globe trauma. Participants Patients undergoing vitrectomy surgery who had sustained open globe trauma. Interventions Triamcinolone acetonide 4 mg/0.1 ml into the vitreous cavity and 40 mg/1 ml sub-Tenon's or standard vitreoretinal surgery and postoperative care. Main outcome measures The primary outcome was the proportion of patients with at least 10 letters of improvement in corrected visual acuity at six months. Secondary outcomes included retinal detachment secondary to proliferative vitreoretinopathy, retinal reattachment, macula reattachment, tractional retinal detachment, number of operations, hypotony, elevated intraocular pressure and quality of life. Health-related quality of life was assessed using the EuroQol Five Domain and Visual Function Questionnaire 25 questionnaires. Results A total of 280 patients were randomised; 129 were analysed from the control group and 130 from the treatment group. The treatment group appeared, by chance, to have more severe pathology on presentation. The primary outcome (improvement in visual acuity) and principal secondary outcome (change in visual acuity) did not demonstrate any treatment benefit for triamcinolone acetonide. The proportion of patients with improvement in visual acuity was 47% for triamcinolone acetonide and 43% for standard care (odds ratio 1.03, 95% confidence interval 0.61 to 1.75, p = 0.908); the baseline adjusted mean difference in the six-month change in visual acuity was -2.65 (95% confidence interval -9.22 to 3.92, p = 0.430) for triamcinolone acetonide relative to control. Similarly, the secondary outcome measures failed to show any treatment benefit. For two of the secondary outcome measures, stable complete retinal reattachment and stable macular retinal reattachment, outcomes for the treatment group were significantly worse for triamcinolone acetonide at the 5% level (respectively, odds ratio 0.59, 95% confidence interval 0.36 to 0.99, p = 0.044 and odds ratio 0.59, 95% confidence interval 0.35 to 0.98, p = 0.041) compared with control in favour of control. The cost of the intervention was £132 per patient. Health economics outcome measures (Early Treatment Diabetic Retinopathy Study, Visual Function Questionnaire 25 and EuroQol Five Dimensions) did not demonstrate any significant difference in quality-adjusted life-years. Conclusions The use of combined intraocular and sub-Tenon's capsule triamcinolone acetonide is not recommended as an adjunct to vitrectomy surgery for intraocular trauma. Secondary outcome measures are suggestive of a negative effect of the adjunct, although the treatment group appeared to have more severe pathology on presentation. Future work The use of alternative adjunctive medications in cases undergoing surgery for open globe trauma should be investigated.

Arepalli S, Wykoff CC, Abraham JR, Lunasco L, Yu H, Hu M, Srivastava SK, Reese JL, Brown D, Ehlers JP. Longitudinal analysis of aqueous humour cytokine expression and OCT-based imaging biomarkers in retinal vein occlusions treated with anti-vascular endothelial growth factor therapy in the IMAGINE study. Eye (Lond) 2023; 37:1928-1935. [PMID: 36220884 PMCID: PMC10275974 DOI: 10.1038/s41433-022-02265-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Revised: 08/14/2022] [Accepted: 09/15/2022] [Indexed: 11/08/2022] Open
Abstract
BACKGROUND/OBJECTIVES Retinal vein occlusion (RVO) is the second most common retinal vascular disorder. Despite promising advances with anti-VEGF therapy, select patients are unresponsive to therapy. A precision medicine-based approach for therapeutic decision-making based on underlying biomarkers may facilitate treatment based on the underlying pathway. This study aims to identify the baseline and longitudinal cytokine profiles of RVO-related macular oedema and correlating these expression profiles with higher order OCT features using a novel retinal segmentation and feature extraction platform. SUBJECTS/METHODS The IMAGINE study is a post-hoc assessment of aqueous humour cytokines with correlation to higher level analysis of imaging studies. OCT scans underwent machine learning enhanced segmentation of the internal limiting membrane (ILM), ellipsoid zone (EZ) and retinal pigment epithelium (RPE), as well as evaluating volumetric fluid metrics. Samples of aqueous humour were obtained at baseline, as well as months 4 and 9 prior to treatment. These samples were analysed for the expression of multiple cytokines. Patients were divided into Responders and Non-Responders based on OCT profiles. Additionally, patients were categorised as a Rebounder if their CST increased by 50% after initial improvement. RESULTS Twenty-six eyes were included. The OCT-based response schema identified 21 Responders (81%) and 5 Non-Responders (19%). VEGF levels directly correlated with intraretinal fluid volume and angiogenin was inversely correlated with fluid indices. Multiple cytokines, including ANGPTL4, were directly correlated with ellipsoid zone disruption. The baseline VEGF levels were significantly higher in all responders compared to Non-Responders (p = 0.02). Rebounders tended to have significantly decreased levels of angiogenin and TIMP-1 (p = 0.019, p = 0.015). CONCLUSIONS Cytokine expression was linked to specific OCT features and treatment response in RVO. Identification of an imaging phenotype that could serve as a surrogate for underlying active disease pathways could enhance treatment decision-making and precision medicine.

Abstract
PURPOSE We examined the effect of ranibizumab with or without laser photocoagulation on retinal sensitivity in eyes with branch retinal vein occlusion. METHODS Prospective randomized control study. Thirty patients with branch retinal vein occlusion received intravitreal injection of ranibizumab in a monthly pro re nata regimen. Fifteen patients received ranibizumab monotherapy alone (monotherapy group). The remaining 15 patients received rescue laser therapy at 3 or 9 months (combined group). The retinal sensitivity was measured at 32 points within central 8°, and the average of the main occlusion side among the 16 upper or 16 lower points was defined as the affected area sensitivity. RESULTS In comparing the monotherapy group and the combined group, the number of injections during the 12 months was 5.4 versus 4.9, the change in retinal thickness ( µ m) was -254 versus -197, the ETDRS letters of improvement was +18.3 versus +19.6, and the change in the affected area sensitivity (dB) was +7.1 versus +4.6. At 12 months, all these results were significantly improved compared with their respective baselines, but none of the differences between the two groups reached statistical significance. CONCLUSION Retinal sensitivity at 12 months improved in both the monotherapy group and the combined group. The additional laser did not reduce the number of injections or further improve visual acuity nor did it affect retinal sensitivity.

Abstract
Purpose To assess the relationship between improving blood flow via arteriovenous (AV) sheathotomy without vitrectomy and the total number of anti-vascular endothelial growth factor injections (VEGF) required to treat branch retinal vein occlusion (BRVO). Methods In this prospective, clinical case series, 16 eyes of 16 patients at the Toho University Sakura Medical Center with best-corrected visual acuity (BCVA) of 20/40 or worse due to macular edema associated with BRVO were analyzed for 12 months. AV sheathotomy was performed without vitrectomy for all cases. On the second day after surgery, anti-VEGF was injected into the operated eye. During the 12-month follow-up after surgery, pro re nata injections were administered when changes in foveal exudation and BCVA were evident. The blood flow of the occluded vein was assessed before and after AV sheathotomy during the operation using laser speckle flowgraphy. The total number of anti-VEGF injections, central retinal thickness (CRT), and BCVA 12 months after surgery were examined. Results The changes in CRT and BCVA from baseline to month 12 were statistically significant (P < 0.01). No additional anti-VEGF injections were required for nine of 16 eyes (56.3%) during the 12 months. The total number of anti-VEGF injections for 12 months correlated with the change rate of blood flow in an occluded vein before and after AV sheathotomy (r = -2.816, P = 0.022). Conclusions and Importance Improved blood flow in occluded vein may reduce the need for anti-VEGF injections in BRVO.

Abstract
BACKGROUND Central retinal vein occlusion and branch retinal vein occlusion are common causes of visual loss due to associated macular oedema. The aim of this review was to assess the effectiveness of interventions improving vision and treating macular oedema in central retinal vein occlusion and branch retinal vein occlusion. METHODS Medical search engines and clinical trial registries were systematically searched. Randomised clinical trials with ≥90 eyes and real-world outcome studies with ≥100 eyes each with ≥6 months follow-up were included. RESULTS There were 11 randomised controlled trials evaluating treatments for central retinal vein occlusion which met the inclusion criteria and 10 for branch retinal vein occlusion. There were 10 real world outcome studies of central retinal vein occlusion and 5 real world outcome studies of branch retinal vein occlusion. Meta-analysis was performed on studies that met the defined inclusion criteria. Main outcomes were change in visual acuity at 6-, 12-, 24- and 36 months by treatment. CONCLUSIONS Intravitreal anti-vascular endothelial derived growth factor is recommended as first line treatment over intravitreal corticosteroid due to its effectiveness and lower rate of ocular adverse events. Best outcomes are achieved when intravitreal treatment is started early. Macular laser may have an adjunctive role in branch retina vein occlusion but not central retinal vein occlusion.

Abstract
Retinal vein occlusion represents the second leading cause of retinal vascular disorders, with a uniform sex distribution worldwide. A thorough evaluation of cardiovascular risk factors is required to correct possible comorbidities. The diagnosis and management of retinal vein occlusion have changed tremendously in the last 30 years, but the assessment of retinal ischemia at baseline and during follow-up examinations remains crucial. New imaging techniques have shed light on the pathophysiology of the disease and laser treatment, once the only therapeutic option, is now only one of the possible approaches with antivascular endothelial growth factors and steroid injections being preferred in most cases. Nowadays long-term outcomes are better than those achievable 20 years ago and yet, many new therapeutic options are under development, including new intravitreal drugs and gene therapy. Despite this, some cases still develop sight-threatening complications deserving a more aggressive (sometimes surgical) approach. The purpose of this comprehensive review is to reappraise some old but still valid concepts and to integrate them with new research and clinical data. The work will provide an overview of the disease's pathophysiology, natural history, and clinical features along with a detailed discussion on the advantages of multimodal imaging and of the different treatment strategies with the aim of providing retina specialists with the most updated knowledge in the field.

Abstract
BACKGROUND Suprachoroidal Drug Delivery has emerged in recent years as a novel promising approach, which may help address the clinical unmet needs in the management of Retinal Vein Occlusion (RVO) associated Macular Edema (ME). In this study, we aim to evaluate the feasibility in regard of the potential efficacy and safety of suprachoroidal injection of Triamcinolone Acetonide (TA) using a microinjector as a mono-treatment of ME due to RVO. METHODS This trial included 16 eyes of 16 patients with RVO associated ME presenting to the department of ophthalmology, Al Mouwasat university hospital, Syria. 4 mg of preserved TA was injected suprachoroidally 4 mm away from the inferotemporal limbus using a patient-customized microinjector. After injection, patients were followed after 1 week then monthly for 3 months. Primary outcome measures included the percentage of participants with best-corrected visual acuity (BCVA) gain≥15 letters and increased intraocular pressure (IOP) ≥ 20 mmHg in months 1,2, and 3, secondary measures included mean change from baseline BCVA, central subfield thickness (CST), and IOP through each of the follow-up points in addition to other measures. RESULTS After injection, BCVA gain≥15 letters occurred in 68.7, 62.5, 50, 50% of patients at week 1 and through months 1,2 and 3 respectively, the mean BCVA improved significantly by 16.4, 16, 14.4, and 11.9 letters (p-value< 0.0005) at week 1 and months 1,2 and 3 respectively. This visual gain was associated with a significant reduction of CST by 290.94 ± 181.76 (week-1) (p-value< 0.0005), 274.31 ± 184.60 (month-1) (p-value< 0.0005), 183.50 ± 165.61 (month-2) (p-value = 0.006) and 137,75 ± 156.25 μm (month-3) (p-value = 0.038). We reported one case of increased IOP ≥ 20 mmHg in the first month that decreased in the second month. The mean change of IOP readings was not statistically significant, with an increase ranging from 0.75 mmHg after the first week (p-value = 0.09) and 0.5 mmHg after 3 months (p-value = 0.72). CONCLUSION This study suggests that suprachoroidal TA could be well tolerated and efficacious as a mono-treatment of RVO associated ME. Future clinical trials are required to confirm its longer-term safety and efficacy and to compare this efficacy with the other therapeutic options. TRIAL REGISTRATION This study was retrospectively registered at clinicaltrials.gov (ID: NCT05038072) on 08/09/2021.

Abstract
BACKGROUND Cone contrast threshold testing (CCT) provides quantitative measurements of color and contrast function to reveal changes in vision quality that are not standard endpoints in clinical trials. We utilize CCT to measure visual function in patients with multiple sclerosis (MS), age-related macular degeneration (AMD), epiretinal membrane (ERM), and retinal vein occlusion (RVO). METHODS Retrospective data was gathered from 237 patients of the Gavin Herbert Eye Institute. Subjects included 17 patients with MS, 45 patients with AMD, 41 patients with ERM, 11 patients with RVO, and 123 healthy controls. Patients underwent the primary measurement outcome, CCT testing, as well as Sloan visual acuity test and spectral domain optical coherence tomography during normal care. RESULTS Color and contrast deficits were present in MS patients regardless of history of optic neuritis. AMD with intermediate or worse disease demonstrated reduced CCT scores. All 3 stages of ERM demonstrated cone contrast deficits. Despite restoration of visual acuity, RVO-affected eyes demonstrated poorer CCT performance than unaffected fellow eyes. CONCLUSIONS CCT demonstrates color and contrast deficits for multiple retinal diseases with differing pathophysiology. Further prospective studies of CCT in other disease states and with larger samples sizes is warranted.

Abstract
Central retinal vein occlusion (CRVO) is a frequent retinal disorder inducing blindness due to the occlusion of the central vein of the retina. The primary cause of the occlusion remains to be identified leading to the lack of treatment. To date, current treatments mainly target the complications of the disease and do not target the primary dysfunctions. CRVO pathophysiology seems to be a multifactorial disorder; several studies did attempt to decipher the cellular and molecular mechanisms underlying the vessel obstruction, but no consensual mechanism has been found. The aim of the current review is to give an overview of CRVO pathophysiology and more precisely the role of the erythroid lineage. The review presents emerging data on red blood cell (RBC) functions besides their role as an oxygen transporter and how disturbance of RBC function could impact the whole vascular system. We also aim to gather new evidence of RBC involvement in CRVO occurrence.

Abstract
PURPOSE To assess the relationship between best-corrected visual acuity (BCVA) and anatomic features in patients with macular edema (ME) related to retinal vein occlusion (RVO). DESIGN Post hoc analysis of 3 clinical trials, which included verified diagnoses, protocol refractions, and the assessment of OCT and fluorescein angiography (FA) images at a masked reading center. PARTICIPANTS Patients diagnosed with RVO-ME. METHODS Correlation analyses were performed to determine the correlation between BCVA and macular anatomy at baseline and at 12 and 24 weeks and between changes from baseline to 12 and 24 weeks. MAIN OUTCOME MEASURES The correlations between BCVA and central subfield thickness (CST), ellipsoid zone (EZ) integrity, intraretinal fluid (IRF), subretinal fluid, central leakage, and ischemia were assessed. RESULTS In a total of 828 eyes with RVO-ME, the mean age, BCVA, and CST at baseline was 64.7 years, 51.1 letters, and 656.9 μm, respectively. At baseline, a moderate negative correlation was observed between BCVA and CST (r = - 0.56, P < 0.001). At weeks 12 and 24, the mean BCVA of eyes with definitely abnormal (absent) EZ was statistically significantly worse than that of eyes with normal EZ. At week 12, a moderate negative correlation was observed between changes in BCVA and changes in CST (r = - 0.35, P < 0.001), with a similar degree of association noted at week 24 (r = - 0.35, P < 0.001). At weeks 12 and 24, eyes that showed any improvement in central IRF showed a greater improvement in BCVA than eyes that showed no improvement worsening (week 12: 463 eyes, 18.3 letters vs. 177 eyes, 13.0 letters, respectively, P < 0.001) and (week 24: 332 eyes, 20.2 letters vs. 131 eyes, 13.3 letters, respectively, P < 0.001). With respect to the correlation between baseline BCVA and fluorescein leakage or capillary nonperfusion, the Pearson correlation coefficients were - 0.41 (P < 0.001) and - 0.16 (P = 0.060), respectively. CONCLUSIONS In addition to CST, there are important clinically relevant relationships between BCVA and both OCT and FA anatomic features in patients with RVO-ME.

Abstract
Intravitreal injection treatment for the management of macular edema as an expression of increased capillary permeability and leakage constitute the mainstay of treatment in retinal vein occlusion. In contrast to diabetic retinopathy or neovascular age-related macular degeneration, permanent and complete functional and morphological restoration can be achieved, as retinal vein occlusions are usually associated with risk factors, but do not represent the manifestation form of an underlying systemic or degenerative chronic disorder; however, successful long-term management of retinal vein occlusion -associated macular edema usually requires intensive and also long-term continued treatment with vascular endothelial growth factor (VEGF) inhibitors or with a less favorable side effect profile, dexamethasone. A functional treatment success can be maintained over the long term by both pro re nata (PRN) or treat and extend (T&E) regimens. In contrast, according to the currently available data, the combination of anti-VEGF administration and grid laser treatment has no additional benefit compared to monotherapy. In patients with recalcitrant macular edema, switching to another intravitreal agent may be considered during the course of treatment, although a true therapeutic benefit with respect to the development of visual acuity has not yet been proven. The current review summarizes the relevant aspects in the management of RVO-associated macular edema and provides the foundations for the application of successful treatment strategies.

Abstract
BACKGROUND AND OBJECTIVE Retinal vein occlusion (RVO) is a major cause of vision loss and elevated intraocular pressure (IOP), high ocular perfusion pressure, and glaucoma are known ophthalmic risk factors for RVO. The aim of this paper is to provide the update on the association and management of high IOP/glaucoma and RVO. METHODS A literature review was performed in PubMed and Medline until May 2022 utilizing specific keywords and cross-matched reference lists. KEY CONTENT AND FINDINGS The association of RVO with high IOP/glaucoma may be attributed to retinal ganglion cell loss due to retinal ischemia in high IOP and glaucoma. As new modalities showed, decreased optic disc perfusion, reduced density of blood vessels in the optic nerve head of glaucoma patients, changes in the peripapillary microvascular parameters, and decreased retinal nerve fiber layer (RNFL) thickness of the optic nerve head of eyes with RVO suggest a common pathway between RVO and glaucoma. Literature suggests the close follow up for glaucoma development among patients with non-arteriovenous (AV) crossing (optic cup or optic nerve sited) RVO in fellow eye and management of elevated IOP among RVO cases treated with anti-vascular endothelial growth factor (VEGF) antibodies/corticosteroids and those with preexisting primary open angle glaucoma (POAG). CONCLUSIONS Determining potential patient responses to treatment and considering therapeutic options are challenging among patients with RVO and glaucoma. However, IOP lowering managements in preventing IOP spikes in patients with preexisting glaucoma and early treatment of macular edema in eyes with RVO is recommended.

Month 60 Outcomes After Treatment Initiation With Anti-Vascular Endothelial Growth Factor Therapy for Macular Edema Due to Central Retinal or Hemiretinal Vein Occlusion. Am J Ophthalmol 2022; 240:330-341. [PMID: 35461831 PMCID: PMC11064059 DOI: 10.1016/j.ajo.2022.04.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Revised: 04/05/2022] [Accepted: 04/06/2022] [Indexed: 11/28/2022]
Abstract
PURPOSE To investigate 5-year outcomes in eyes initially treated with aflibercept or bevacizumab for macular edema due to central retinal or hemiretinal vein occlusion. METHODS Long-term follow-up (LTF) after a randomized clinical trial from 64 centers in the United States. Participants were followed up to 60 months and treated at investigator discretion after completing the 12-month treatment protocol. Main outcomes were visual acuity letter score (VALS) and central subfield thickness (CST) on optical coherence tomography. RESULTS Seventy-five percent (248/330) of eligible participants completed at least 1 visit between months 24 and 60, and 45% completed the month 60 visit. Among participants completing month 60, overall mean VALS improvement over baseline was 13.5 (95% CI: 9.6, 17.5), less than the mean improvement of 20.6 (95% CI: 18.7, 22.4) observed at month 12, with no significant differences between originally assigned study groups. Further, 66% (99/150) had at least 1 treatment between months 48 and 60 with a mean (SD) of 3.41 (3.69) treatments over this period. Mean CST was 671 μm at baseline and 261 μm (95% CI: 241.2, 280.9) at month 60. CONCLUSIONS Although VALS improved substantially when patients were treated per protocol through month 12, improvement lessened when treatment was at investigator discretion and fewer treatments were received although VALS remained markedly improved over baseline through year 5. Most patients continued to receive treatment in year 5. This suggests that continued monitoring and, if warranted, treatment with anti-VEGF therapy benefits patients with macular edema associated with central retinal or hemiretinal vein occlusion.

Abstract
Despite many studies, optimal treatment sequences or intervals are still questionable in retinal vein occlusion (RVO) macular edema. The aim of this study was to examine the real-world treatment patterns of RVO macular edema. A retrospective analysis of the Observational Medical Outcomes Partnership Common Data Model, a distributed research network, of four large tertiary referral centers (n = 9,202,032) identified 3286 eligible. We visualized treatment pathways (prescription volume and treatment sequence) with sunburst and Sankey diagrams. We calculated the average number of intravitreal injections per patient in the first and second years to evaluate the treatment intensities. Bevacizumab was the most popular first-line drug (80.9%), followed by triamcinolone (15.1%) and dexamethasone (2.28%). Triamcinolone was the most popular drug (8.88%), followed by dexamethasone (6.08%) in patients who began treatment with anti-vascular endothelial growth factor (VEGF) agents. The average number of all intravitreal injections per person decreased in the second year compared with the first year. The average number of injections per person in the first year increased throughout the study. Bevacizumab was the most popular first-line drug and steroids were considered the most common as second-line drugs in patients first treated with anti-VEGF agents. Intensive treatment patterns may cause an increase in intravitreal injections.

Abstract
Anti-vascular endothelial growth factor treatment for macular edema secondary to branch retinal vein occlusion generally provides good visual acuity (VA) improvement but may require repeated injections for years. To reduce the number of patients who suffer from avoidable VA loss caused by treatment drop-out, providing prospects of the correlation between expected vision improvement and required number of injections at the early stages of treatment may be helpful. In this post hoc analysis of the phase IV, randomized, open-label ZIPANGU study, we investigated the correlation between the data from Month 2 and Month 12 in terms of VA and required ranibizumab injection numbers. Fifty-nine patients were evaluated (ranibizumab monotherapy, 29; combination therapy, 30). In the monotherapy group, patients who received 1 and 3 injections by Month 2 received a mean total of 2.8 and 8.3 injections during the year, respectively. Data from the combination group were similar. The correlation coefficients for VA scores at Months 2 and 12 were 0.60 and 0.51 for the monotherapy and combination groups, respectively (both p < 0.01). Based on VA and injection numbers at Month 2 of treatment, physicians could provide rough prospects on patients’ expected final VA and required number of injections.

Abstract
Importance Intravitreal anti-vascular endothelial growth factor (VEGF) injections are commonly used to treat eyes with macular edema secondary to hemiretinal vein occlusion (HRVO) or central retinal vein occlusion (CRVO). Information on whether differences exist in outcomes after anti-VEGF therapy can help guide treatment for each of the different disease types. Objective To compare baseline characteristics, treatment burden, and outcomes of macular edema treatment in participants with HRVO with those of participants with CRVO. Design, Setting, and Participants This post hoc outcome analysis from the Study of Comparative Treatments for Retinal Vein Occlusion 2 randomized clinical trial included 362 participants with macular edema caused by HRVO or CRVO treated at 66 US sites. Randomization began in September 2014, and the last month 24 follow-up visit occurred in February 2018. Data were analyzed from April 2020 to May 2021. Interventions Eyes were initially randomized to 6 monthly intravitreal injections of aflibercept or bevacizumab and were treated according to protocol between months 6 to 12 depending on 6-month outcome. After month 12, patients were treated per investigator discretion and observed through month 60. Main Outcomes and Measures Mean visual acuity letter score (VALS). Results Of 362 included patients, 157 (43.4%) were female, and the mean (SD) age was 68.9 (12.0) years. Outcome data were analyzed up to month 24 owing to substantial missing data at later visits. A significantly greater proportion of participants with HRVO than those with CRVO were Black (37% vs 11%). Treatment rates between months 12 to 23 were 0.36 (95% CI, 0.32-0.40) injections per month for patients with CRVO and 0.28 (95% CI, 0.19-0.36) for patients with HRVO (P = .11). The mean VALS from months 1 to 24 of an HRVO study eye exceeded that of a CRVO study eye by 5.5 (95% CI, 1.5-9.5; P = .01), consistent with the magnitude of the VALS difference between eyes with CRVO and HRVO at baseline. Eyes with CRVO presented at baseline with more macular edema than eyes with HRVO (difference in central subfield thickness [CST], 86 μm; 95% CI, 48-124; P < .001), with no difference in CST between the groups throughout months 1 to 24. Conclusions and Relevance Black race was more prevalent among participants with HRVO than CRVO, and no differences were observed in the frequency of treatments for macular edema between eyes with CRVO and HRVO. Although eyes with CRVO presented with worse visual acuity and more macular edema on average than did eyes with HRVO, the magnitude of VALS improvement, central retinal thickness in response to anti-VEGF therapy, and treatment burden were similar between the groups.

Abstract
The use of steroids to treat macular edema (ME) is a research hotspot in ophthalmology. We utilized CiteSpace and VOSviewer software to evaluate the Web of Science Core Collection publications and to build visualizing maps to describe the research progress in this topic. There were 3,252 publications for three decades during 1988–2021. The number of studies was low during the first 14 years but has risen consistently in the following two decades. The average publications per year were only 4.8 during 1988–2002, which jumped to 113 per year during 2003–2012, and 227 per year during 2013–2021. These publications came from 83 countries/regions, with the United States, Germany, and Italy leading positions. Most studies were published in Investigative Ophthalmology Visual Science, and Ophthalmology was the most cited journal. We found 9,993 authors, with Bandello F having the most publications and Jonas JB being the most frequently co-cited. According to our research, the most popular keyword is triamcinolone acetonide (TA). Macular edema, diabetic macular edema (DME), retinal vein occlusion (RVO), dexamethasone (DEX), fluocinolone acetonide (FA), and some other keywords were commonly studied in this field. In conclusion, the bibliometric analysis provides a comprehensive overview of steroid hotspots and developmental tendencies in the macular edema study. While anti-VEGF therapy is the first-line treatment for DME and RVO-induced macular edema, steroids implant is a valid option for these DME patients not responding to anti-VEGF therapy and non-DME patients with macular edema. Combined therapy with anti-VEGF and steroid agents is vital for future research.

Abstract
INTRODUCTION The pathogenesis of retinal vein occlusion (RVO) is extremely complex and includes several mediators. These mediators represent potential drug targets that can be used in the development of intravitreal drugs. AREAS COVERED PubMed/MEDLINE databases were accessed between April-May 2021 to find the most relevant scientific papers regarding drug targets and therapeutic implications in RVO, focusing on current therapeutic options and potential cornerstones of future advances in treatment. EXPERT OPINION Before the introduction of intravitreal therapies, the visual outcome following a diagnosis of RVO was extremely poor. Anti-VEGF and corticosteroid treatments have radically changed RVO prognosis, helping to preserve patients' visual function and their quality of life. According to current clinical data, anti-VEGF and corticosteroid drugs are associated with both pros and cons; the present recommendation is to employ anti-VEGF molecules as a first-line treatment. Advances in our understanding of the biomolecular characteristics of RVO offer a solid basis for the development of new therapeutic targets and treatments.

Abstract
Purpose: To evaluate the results of treatment according to the method of intravitreal injection of bevacizumab for macular edema due to branch retinal vein occlusion (BRVO). Methods: The clinical records of macular edema patients were analyzed retrospectively for a total of 62 eyes of 62 patients who were injected with bevacizumab into the vitreous as the first treatment for BRVO. Best-corrected visual acuity (BCVA), the findings of spectral-domain optical coherence tomography before and after injection, and prognosis-related factors were evaluated for 21 eyes that received the initial three monthly loading treatments and the 41 eyes that did not. Results: Significant improvement in BCVA was observed in the group having received the initial three injections compared with the group who did not receive the injections at 3, 6, and 12 months (<i>p</i> = 0.025, <i>p</i> = 0.019, and <i>p</i> = 0.008, respectively). The central macular thickness (CMT) showed greater improvement in the initial three injections group than the group without at 6 months (<i>p</i> = 0.034). Multivariate regression showed that the duration from the onset, the three loadings, BCVA, disorganization of the retinal inner layer (DRIL), and choroidal thickness were predictors related to visual gain (<i>p</i> = 0.044, <i>p</i> = 0.047, <i>p</i> = 0.004, <i>p</i> = 0.045, and <i>p</i> = 0.034, respectively). Age, three loadings, BCVA, and DRIL were predictors related to final visual acuity (<i>p</i> = 0.045, <i>p</i> = 0.046, <i>p</i> = 0.002, and <i>p</i> = 0.034, respectively). Duration from the onset, CMT, and choroidal thickness were predictors related to CMT improvement (<i>p</i> = 0.042, <i>p</i> = 0.009, and <i>p</i> = 0.015, respectively). Conclusions: In macular edema of BRVO, the initial three monthly intravitreal injections of bevacizumab provided superior treatment outcomes regarding short-term functional and anatomical improvements and long-term functional improvement, compared with methods that did not treat with the initial three monthly injections.

BACKGROUND AND OBJECTIVES To describe the presentation, management, and clinical outcomes of branch retinal vein occlusion (BRVO) in African American patients compared to patients of other racial or ethnic backgrounds. PATIENTS AND METHODS This retrospective cohort study included eyes diagnosed with BRVO and macular edema at a tertiary referral center. Presenting features, treatment, and outcomes were compared based on racial or ethnic backgrounds. RESULTS The study included 285 eyes: 21.8% African American, 78.2% other. African American patients were more likely to have comorbid diabetes (P = .012), open-angle glaucoma (P < .001), and to present with subretinal fluid (P = .049); multivariate analysis showed race and ethnicity alone may not fully explain presenting subretinal fluid (odds ratio = 2.807; 95% CI, 0.997 to 7.903; P = .051). There was no difference in other comparisons of clinical outcomes or treatment burden, including visual acuity, duration, or treatment method. CONCLUSIONS Despite significant differences at presentation, the management and outcomes of BRVO did not differ significantly between African American patients and patients of other racial and ethnic backgrounds.

Abstract
PURPOSE To analyze the 100 most cited articles pertaining to endophthalmitis using bibliometric analysis. METHODS An all-time Web of Science literature search and refined to peer-reviewed articles in the field of ophthalmology with the keyword "endophthalmitis" was completed. Total citation count of articles published pertaining to endophthalmitis, topic, incidence rate, publishing journals, year published, language, country of origin, number of authors, names of the first and last authors, study type, and number of patients/eyes studied. RESULTS The top 100 most cited articles pertaining to endophthalmitis had a mean citation count of 362.92, with a range of 175 to 3583. They were published in 20 peer-reviewed journals, with Ophthalmology publishing the most (n = 42). Thirteen different countries were represented, with the majority (n = 77) originating from the USA. The most common study type was clinical experiences (n = 52), though eight of the top ten were clinical trials. The number of patients varied widely, represented by a mean of 9680, but with a median of only 229. The majority (n = 67) examined the incidence of endophthalmitis which included 24 articles after anti-vascular endothelial growth factor injections, 18 after ocular surgeries/procedures, 15 after intraocular steroid injections, eight after chemotoxic drug use, and three after ocular injuries. CONCLUSION This bibliographic study serves as a unique historical analysis of the top 100 cited scholarly articles pertaining to endophthalmitis with many of the articles related to post-procedural endophthalmitis.

[PMID: 34204557 PMCID: PMC8235093 DOI: 10.3390/life11060572] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2021] [Revised: 06/07/2021] [Accepted: 06/15/2021] [Indexed: 11/16/2022] Open
Abstract
We aimed to investigate the relationship between subfoveal choroidal thickness (SCT) and treatment outcomes of intravitreal aflibercept (IVA) for macular edema (ME) due to branch retinal vein occlusion (BRVO). We retrospectively evaluated 46 patients with treatment-naive BRVO-ME who underwent IVA treatment between March 2016 and February 2017. There was no significant difference in visual acuity within 6 months (0.29 ± 0.20 vs. 0.27 ± 0.19, p = 0.338), the mean central foveal thickness improvement (332.0 ± 162.2 μm vs. 303.9 ± 166.6 μm, p = 0.492), and the mean number of IVA injections (1.7 ± 0.7 vs. 1.6 ± 0.7 times, p = 0.658) between the SCT thickened (n = 26 patients, 26 eyes) and SCT non-thickened groups (n = 20 patients, 20 eyes). The rate of ME recurrence was significantly lower in the SCT decreased group (6/17 eyes (35.2%) vs. 19/30 eyes (63.3%); p = 0.038). In conclusion, pretreatment choroidal thickening does not affect the therapeutic effect of IVA for BRVO, but ME recurrence was lower in cases of treatment-related choroidal thinning. Thus, changes in SCT may be a therapeutic indicator of IVA for acute BRVO.

Comparison between two intravitreal injection techniques with respect to fluid reflux, intraocular pressure, and therapeutic effect. Oman J Ophthalmol 2021; 14:33-37. [PMID: 34084032 PMCID: PMC8095307 DOI: 10.4103/ojo.ojo_67_2020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2020] [Revised: 04/05/2020] [Accepted: 06/07/2020] [Indexed: 12/01/2022] Open
Abstract
CONTEXT: Effect of fluid reflux on intraocular pressure (IOP) and therapeutic benefits. AIMS: The aim of this study is to compare two intravitreal injection techniques in terms of fluid reflux, short-term IOP changes, and therapeutic effect. SETTINGS AND DESIGN: A prospective, double-blinded, randomized interventional study. SUBJECTS AND METHODS: Sixty eyes were randomly allocated to two groups (direct intravitreal injection technique and oblique intravitreal injection technique). IOP was measured before and immediately after the injection of 0.1 ml comprising of bevacizumab (1.25 mg/0.05 ml) and dexamethasone (0.2 mg/0.05 ml) and then at 30 min after the injection. Occurrence and amount of vitreous reflux were recorded. Best-corrected visual acuity (BCVA) and central macular thickness (CMT) were assessed preinjection and 6 weeks postinjection. RESULTS: IOP (mmHg ± standard deviation) increased significantly immediately after injection to 24.30 ± 3.02 (direct intravitreal injection) and 31.50 ± 3.49 (oblique intravitreal injection). These pressure rise differed significantly between both groups (mean difference: 7.2, P < 0.0001). Thirty minutes after injection, there was no significant difference in IOP increase between the groups. Occurrence and amount of fluid reflux were significantly higher with direct intravitreal injection. There was no significant difference in BCVA and CMT outcome between both groups. CONCLUSIONS: Direct intravitreal injection technique has lower rise in IOP and higher incidence of fluid reflux than the oblique intravitreal technique. Fluid reflux does not cause a therapeutic compromise in terms of BCVA or CMT changes, so the reflux fluid must be the vitreous not the drug. Thus, direct injection technique seems to be the preferred technique.

Real-World Outcomes in Patients with Branch Retinal Vein Occlusion- (BRVO-) Related Macular Edema Treated with Anti-VEGF Injections Alone versus Anti-VEGF Injections Combined with Focal Laser. J Ophthalmol 2021; 2021:6641008. [PMID: 34104482 PMCID: PMC8159650 DOI: 10.1155/2021/6641008] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2020] [Accepted: 05/07/2021] [Indexed: 11/17/2022] Open
Abstract
The purpose of this study was to assess outcomes in a real-world nonclinical trial setting of antivascular endothelial growth factor (VEGF) injections alone vs. focal laser combined with anti-VEGF injections in patients with branch retinal vein occlusion- (BRVO-) related macular edema (ME). This study included 88 BRVO with ME patients who were treated over three years at both a tertiary referral center in the Birmingham metropolitan area and satellites in rural Alabama. One group received only anti-VEGF injections (n = 56); the other group received both anti-VEGF injections and focal laser (n = 32). The following outcome measures were evaluated: initial and final visual acuities (VA), initial central subfield thickness (CST) on OCT, number of injections, number of lasers, percentage of patients with a gain of 3 lines of VA, percentage of patients with VA better than or equal to 20/40, and percentage of patients with VA worse than or equal to 20/200. We found that there was no difference in initial VA (p=0.913) or CST (p=0.961) between the two groups. The injection only group required a median of 7 injections, while the combination group required a median of 4 injections, but this was not a statistically significant difference (p=0.117). There was no difference in final VA (p=0.414) or any of the other visual outcomes between the two groups. In conclusion, focal laser did not decrease the number of injections required or improve the VA in BRVO-related ME. Although visual outcomes were similar in both groups, focal laser does not appear to be of additional benefit in BRVO-related ME in the anti-VEGF era.

Abstract
Anti-vascular endothelial growth factor (anti-VEGF) therapy currently plays a central role in the treatment of numerous retinal diseases, most notably exudative age-related macular degeneration (eAMD), diabetic retinopathy and retinal vein occlusions. While offering significant functional and anatomic benefits in most patients, there exists a subset of 15–40% of eyes that fail to respond or only partially respond. For these cases, various treatment options have been explored with a range of outcomes. These options include steroid injections, laser treatment (both thermal therapy for retinal vascular diseases and photodynamic therapy for eAMD), abbreviated anti-VEGF treatment intervals, switching anti-VEGF agents and topical medications. In this article, we review the effectiveness of these treatment options along with a discussion of the current research into future directions for anti-VEGF-resistant eyes.

Abstract
Open globe trauma is the major cause for single eye blindness that stem from subsequent proliferative vitreoretinopathy (PVR). Though biomaterials and tissue engineering have significantly advanced drug delivery and management of human diseases, currently there is no effective drug formulation or device to pharmacologically mitigate PVR formation after open-globe eye trauma. This highlighted the challenge we are facing to bring the technology from bench to bedside. The current study reported an engineered episcleral drug film using biodegradable material, Poly(L-lactide)-co-poly(ɛ-caprolactone), and triamcinolone acetonide (TA) as a model drug. The film can be conveniently sized into any shape to fit the configuration of the eye globe trauma and easily installed onto the ruptured sclera during primary trauma repair surgery. The film allows therapeutic TA to slow release for at least 6 months without toxicity and demonstrated a significant benefit to reduce the odds of developing severe PVR by 5.7 times when compared with a no-drug film control on a rabbit trauma PVR model. Our results suggested this micro episcleral drug film as promising drug delivery carrier for the targeted treatment of various unwanted retinal proliferation diseases.

Abstract
The role of photocoagulation in retinal vein occlusion (RVO) has been studied since 1974. The most serious complications of central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO) are: (i) visual deterioration, most commonly due to macular edema, and (ii) the development of ocular neovascularization (NV), particularly neovascular glaucoma (NVG), with hazardous consequences for vision and even the eye itself. Before discussing the role of photocoagulation in the management of NV and macular edema in RVO, it is crucial to gain a basic scientific understanding of the following relevant issues: classification of RVO, ocular NV in RVO, and the natural history of macular edema and visual outcome of RVO. These topics are discussed. In CRVO, ocular NV is a complication of ischemic CRVO but not of nonischemic CRVO. Photocoagulation has been advocated to prevent and/or treat the development of ocular NV and NVG. Since NVG is the most dreaded, intractable and blinding complication of ischemic CRVO, the role of photocoagulation and its management are discussed. Findings of three randomized, prospective clinical trials dealing with photocoagulation in ischemic CRVO are discussed. The role of photocoagulation in the management of ocular NV and macular edema in BRVO, and three randomized, prospective clinical trials dealing with those are discussed. Recent advent of intravitreal anti-VEGF and corticosteroid therapies has drastically changed the role of photocoagulation in the management of macular edema and NV in CRVO and BRVO. This is discussed in detail.

Abstract
In recent years, an increasing amount of attention has been paid to medicinal products as possible risk factors in the development of eye diseases. The frequency of diagnosed drug-induced uveitis is growing yearly, which can be attributed to the appearance of new drugs - biological agents (immune checkpoint inhibitors, BRAF and MEK inhibitors, vascular endothelial growth factor inhibitors, tumor necrosis factor-α inhibitors), as well as systemic bisphosphonates and some antiviral drugs. The time interval between the beginning of the drug use and the appearance of uveitis symptoms varies from several days to months. Common symptoms include eye pain, photophobia, the appearance of floating opacities, and reduced vision associated with active inflammatory changes in the retina and optic nerve and outcomes of those inflammations. Timely diagnosis, cancellation of the drug that caused uveitis and appointment of adequate anti-inflammatory therapy in most cases effectively stops the symptoms of the disease, which determines the relevance of attention to the prevalence, pathogenesis, diagnosis and treatment of drug-induced uveitis.

Abstract
BACKGROUND AND OBJECTIVE To identify factors associated with successful treatment discontinuation in eyes with retinal vein occlusions (RVOs) and macular edema (ME) in real-world settings. PATIENTS AND METHODS Retrospective study of 214 eyes with RVO and ME with 24-month follow-up at five academic centers. Regression analyses identified factors associated with (1) successful treatment discontinuation for at least 6 months without fluid recurrence and (2) best-corrected visual acuity (BCVA) at 24 months. RESULTS Forty percent of eyes with branch RVO and 35% with central RVO (CRVO) / hemi-retinal RVO (HRVO) successfully discontinued therapy without fluid recurrence, with median time to discontinuation of 6 and 7 months, respectively. Lower 6-month central subfield thickness was associated with greater likelihood of treatment discontinuation within 24 months for eyes with CRVO/HRVO (P = .001), whereas better 6-month BCVA was associated with better 24-month BCVA for all RVO subtypes (P < .001). CONCLUSION Early anatomic response at 6 months is associated with greater likelihood of stopping treatments. [Ophthalmic Surg Lasers Imaging Retina. 2021;52:84-92.].

Abstract
Purpose: This work reports the duration, safety, and viability of intravitreal slurry triamcinolone acetonide (TA; 1.0 mL of 40-mg/mL TA centrifuge concentrated into a 0.1-mL pellet) to treat cystoid macular edema (CME). Methods: A retrospective, consecutive review was conducted of patients undergoing intravitreal slurry TA injections, July 2009 to December 2018. Results: In 143 eyes of 120 patients, slurry TA resolved CME for a mean of 327.15 (SD = 213.11) days, or 10.76 (SD = 7.00) months, per intravitreal injection (n = 466). In 100 eyes requiring multiple injections (n = 423), mean duration was 270.95 (SD = 177.14) days, or 8.91 (SD = 5.82) months, between injections. In 43 single-injection eyes, duration was 749.30 (SD = 483.17) days, or 24.63 (SD = 15.88) months. Mean duration decreased from 337.89 (SD = 210.46) days, or 11.11 (SD = 6.92) months, in nonvitrectomized eyes to 279.74 (SD 179.63) days, or 9.20 (SD = 5.91) months, in vitrectomized eyes (n = 74 injections, t = 2.24, P = .014, 1-tailed). Central foveal thickness as shown on optical coherence tomography decreased by 173.89μ (SD = 147.56μ), from 459.16μ (SD = 47.14μ) to 285.27μ (SD = 77.27μ; t = –25.31, P < .001), within 43.41 days (SD = 36.86). Visual acuity improved from 20/100 (logMAR 0.70, SD = 0.33) to 20/74 (logMAR 0.57, SD = 0.31; SD = 0.21; t = –11.01, P < .001), within 33.98 (SD 24.98) days. Fifteen of 31 phakic eyes (48.39%) underwent cataract extraction. Fifty-seven eyes (39.86%) developed a steroid response (> 10 mm Hg increase from baseline) 94.79 days (SD = 85.52 days), or 3.11 (SD = 2.81) months, following injection. Conclusions: A single injection of slurry TA lasted on average 10.76 months with significant improvement of CME and visual acuity. Adverse ocular effects were comparable to currently available, long-term, implantable steroids. Slurry TA appears to be an easily reproducible, safe, and cost-effective alternative to long-term intraocular steroid delivery.

Abstract
PURPOSE To investigate the efficacy of intravitreal dexamethasone implants (DEX) after anti-VEGF failure in retinal vein occlusion macular oedema. METHODS Retrospective cohort study of DEX implant (0.7 mg) given after anti-VEGF 'failure'. Switch to DEX occurred if a ⩽ +5 ETDRS letter gain and ⩽20% reduction in central subfield thickness was present following ⩾6 consecutive anti-VEGF injections. The primary endpoint was VA change 30 days after DEX. Secondary outcomes were peak VA change, VA change at monthly timepoints, percentage achieving 15-letter gain, central subfield thickness (CST) and intraocular pressure (IOP). RESULTS Sixty-two injections in 62 patients associated with 26% central retinal vein occlusion (CRVO) and 74% branch retinal vein occlusion (BRVO) were eligible. There was a modest, significant improvement in mean VA change at 30 days compared to baseline (+6 letters, 95% CI +2.2 to +9.1 letters, p < 0.01). DEX implant significantly improved mean peak VA change compared to preceding anti-VEGF by +18.1 letters in CRVO (p = 0.002) and +13.2 letters in BRVO (p < 0.0001). IOP peaked between 30 and 60 days following injection, with 31% of CRVO and 11% of BRVO patients experiencing an IOP ⩾ 25 mmHg. CONCLUSION DEX implant provides useful rescue therapy in cases of anti-VEGF 'failure' for macular oedema following retinal vein occlusion, resulting in improved functional outcomes at 30 days.

Abstract
Acute retinal vascular occlusions are common causes of visual impairment. Although both retinal artery occlusions and retinal vein occlusions are associated with increased age and cardiovascular risk factors, their pathophysiology, systemic implications, and management differ substantially. Acute management of retinal artery occlusions involves a multidisciplinary approach including neurologists with stroke expertise, whereas treatment of retinal vein occlusions is provided by ophthalmologists. Optimisation of systemic risk factors by patients' primary care providers is an important component of the management of these two disorders.

Vinković M, Bosnar D, Tedeschi Reiner E, De Salvo G, Matić S. COMBINED TREATMENT WITH BEVACIZUMAB AND TRIAMCINOLONE ACETONIDE FOR MACULAR EDEMA DUE TO RETINAL VEIN OCCLUSION. Acta Clin Croat 2020; 59:569-575. [PMID: 34285426 PMCID: PMC8253081 DOI: 10.20471/acc.2020.59.04.01] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2017] [Accepted: 01/09/2018] [Indexed: 11/24/2022] Open
Abstract
The purpose of this study was to determine the efficacy of combined intravitreal bevacizumab and triamcinolone in the treatment of macular edema due to retinal vein occlusion. A prospective randomized trial was conducted in the Department of Ophthalmology, Osijek University Hospital Centre in Osijek including 51 patients divided into three groups depending on the drug received. The first group received 1.25 mg intravitreal bevacizumab, the second group received 1 mg intravitreal triamcinolone, and the third group received a combination of 1.25 mg bevacizumab and 1 mg intravitreal triamcinolone on the same day. Changes in the central macular thickness, intraocular pressure and visual acuity were monitored during the follow up period. The retinal perfusion status was evaluated by fluorescein angiography. The group that received combined treatment had better outcome in terms of reduction of macular thickness. There was no statistically significant intraocular pressure elevation among the three treatment groups or within each group of patients. A positive trend regarding visual improvement was observed in the group receiving combined treatment in spite of the lowest initial visual acuity, highest value of macular thickness and longest mean duration of symptoms. In conclusion, combined treatment with bevacizumab and triamcinolone for the treatment of retinal vein occlusion is more potent, safe, efficient and cost-effective. It can also be recommended because fewer injections are needed in patients undergoing treatment for macular edema.

Effects of Switching from Anti-VEGF Treatment to Triamcinolone Acetonide in Eyes with Refractory Macular Edema Associated with Diabetic Retinopathy or Retinal Vein Occlusion. BIOMED RESEARCH INTERNATIONAL 2020; 2020:4529850. [PMID: 33274211 PMCID: PMC7695504 DOI: 10.1155/2020/4529850] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/09/2020] [Revised: 10/23/2020] [Accepted: 10/29/2020] [Indexed: 01/13/2023]
Abstract
Purpose To evaluate the efficacy of switching from intravitreal antivascular endothelial growth factor (VEGF) agents to triamcinolone acetonide (TA) in eyes with diabetic macular edema (DME) or with retinal vein occlusion-associated macular edema (RVO-ME) on the resolution of the macular edema (ME). Methods The medical records of 11 eyes of 11 patients with DME and 9 eyes of 9 patients with RVO-ME whose MEs were refractory to anti-VEGF treatment were reviewed. The central retinal thickness (CRT), best-corrected visual acuity (BCVA), intraocular pressure (IOP), and the mean interval of the recurrences were measured during the anti-VEGF treatment and after switching to the TA injections. Results Switching to TA injections significantly increased the mean interval for recurrences from 9.2 ± 2.7 weeks to 22.3 ± 12.9 weeks in eyes with DME (P = 0.006). In eyes with RVO-ME, the mean period of recurrence was 12.3 ± 5.6 weeks before and 11.6 ± 4.4 weeks after the switch (P = 0.44). The mean interval for recurrence was extended to more than 8 weeks in 7 of 11 eyes with DME, but none of the eyes with RVO-ME had a prolongation of more than 4 weeks. An elevation of the IOP was observed in 3 of the 20 eyes after the TA injection. Conclusions These findings indicate that switching to TA injections can be a good option for DME eyes refractory to anti-VEGF injections but not for the RVO-ME eyes.

Abstract
PURPOSE To evaluate the presence of macular edema secondary to retinal vein occlusion (RVO)-both central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO)-3 years after diagnosis in patients who underwent intravitreal therapy and to identify potential prognostic factors and biomarkers of persistent macular edema. METHODS National multicenter, observational, exploratory, retrospective cohort study of 104 consecutive patients with macular edema secondary to RVO diagnosed from January 2014 to December 2015 with minimum 3-year follow-up time. Data analyzed included best-corrected visual acuity (BCVA), clinical and demographic data, and spectral domain optical coherence tomography parameters. RESULTS At final observation, median baseline central retinal thickness significantly improved from baseline 538 to 290 μm (p < 0.001) and complete macular edema resolution was achieved in 51.0% of patients (56.3% and 42.5% in BRVO and CRVO patients, respectively). BCVA also improved (p < 0.01). Logistic regression analysis revealed a relationship between recurrence of macular edema and disorganization of retinal inner layers (DRIL) at baseline (odds ratio = 2.88; p = 0.013). CONCLUSION Good long-term anatomical and functional outcomes are achieved with intravitreal treatments in RVO patients. Anatomical success and visual gains seen in the first year were maintained throughout the entire follow-up, though DRIL is a major risk factor for recurrence.

Abstract
BACKGROUND Multiple intravitreal pharmacotherapies including different anti-vascular endothelial growth factors (VEGF), intravitreal steroids, and combined therapy with anti-VEGF and steroids are available for patients with macular edema secondary to retinal vein occlusion (RVO). However, the recommendation of multiple therapies remains unknown. This study aims to evaluate the efficacy and safety of multiple intravitreal pharmacotherapies in patients with macular edema secondary to RVO. METHODS We will systematically search the PubMed, Embase, and the Cochrane library for eligible studies. Randomized controlled trials (RCTs) with intravitreal pharmacotherapies for patients with macular edema secondary to RVO will be included. The Cochrane Collaboration's tool will be used to assess the risk of bias in the randomized trial. The primary outcome is the mean change in BCVA from baseline. The secondary outcomes are the proportion of patients who gained ≥15 letters in BCVA from baseline, the mean change in central retinal thickness from baseline and the number of serious adverse events. RESULTS The result will obtain a comprehensive treatment recommendation for macular edema secondary to RVO. CONCLUSION The results of the network meta-analysis will be submitted in a peer-reviewed journal for publication. ETHICAL STATEMENT This article does not contain any studies with human or animal subjects performed by any of the authors.

Abstract
BACKGROUND Branch retinal vein occlusion (BRVO) is one of the most commonly occurring retinal vascular abnormalities. The most common cause of visual loss in people with BRVO is macular oedema (MO). Grid or focal laser photocoagulation has been shown to reduce the risk of visual loss. Limitations to this treatment exist, however, and newer modalities may have equal or improved efficacy. Antiangiogenic therapy with anti-vascular endothelial growth factor (anti-VEGF) has recently been used successfully to treat MO resulting from a variety of causes. OBJECTIVES To investigate the efficacy and gather evidence from randomised controlled trials (RCTs) on the potential harms of anti-vascular endothelial growth factor (VEGF) agents for the treatment of macular oedema (MO) secondary to branch retinal vein occlusion (BRVO). SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2019, Issue 6); MEDLINE Ovid; Embase Ovid; the ISRCTN registry; ClinicalTrials.gov; and the WHO ICTRP. The date of the last search was 12 June 2019. SELECTION CRITERIA We included randomised controlled trials (RCTs) investigating BRVO. Eligible trials had to have at least six months' follow-up where anti-VEGF treatment was compared with another treatment, no treatment, or placebo. We excluded trials where combination treatments (anti-VEGF plus other treatments) were used; and trials that investigated the dose and duration of treatment without a comparison group (other treatment/no treatment/sham). DATA COLLECTION AND ANALYSIS Two review authors independently extracted the data using standard methodological procedures expected by Cochrane. The primary outcome was the proportion of participants with an improvement from baseline in best-corrected visual acuity of greater than or equal to 15 letters (3 lines) on the Early Treatment in Diabetic Retinopathy Study (ETDRS) Chart at six months and 12 months of follow-up. The secondary outcomes were the proportion of participants who lost greater than or equal to 15 ETDRS letters (3 lines) and the mean visual acuity (VA) change at six and 12 months, as well as the change in central retinal thickness (CRT) on optical coherence tomography from baseline at six and 12 months. We also collected data on adverse events and quality of life (QoL). MAIN RESULTS We found eight RCTs of 1631 participants that met the inclusion criteria after independent and duplicate review of the search results. These studies took place in Europe, North America, Eastern Mediterranean region and East Asia. Included participants were adults aged 18 or over with VA of 20/40 or worse. Studies varied by duration of disease but permitted previously treated eyes as long as there was sufficient treatment-free interval. All anti-VEGF agents (bevacizumab, ranibizumab and aflibercept) and steroids (triamcinolone and dexamethasone) were included. Overall, we judged the studies to be at moderate or unclear risk of bias. Four of the eight studies did not mask participants or outcome assessors, or both. One trial compared anti-VEGF to sham. At six months, eyes receiving anti-VEGF were significantly more likely to have a gain of 15 or more ETDRS letters (risk ratio (RR) 1.72, 95% confidence interval (CI) 1.19 to 2.49; 283 participants; moderate-certainty evidence). Mean VA was better in the anti-VEGF group at six months compared with control (mean difference (MD) 7.50 letters, 95% CI 5.29 to 9.71; 282 participants; moderate-certainty evidence). Anti-VEGF also proved more effective at reducing CRT at six months (MD -57.50 microns, 95% CI -108.63 to -6.37; 281 participants; lower CRT is better; moderate-certainty evidence). There was only very low-certainty evidence on adverse effects. There were no reports of endophthalmitis. Mean change in QoL (measured using the National Eye Institute Visual Functioning Questionnaire VFQ-25) was better in people treated with anti-VEGF compared with people treated with sham (MD 7.6 higher score, 95% CI 4.3 to 10.9; 281 participants; moderate-certainty evidence). Three RCTs compared anti-VEGF with macular laser (total participants = 473). The proportion of eyes gaining 15 or more letters was greater in the anti-VEGF group at six months (RR 2.09, 95% CI 1.44 to 3.05; 2 studies, 201 participants; moderate-certainty evidence). Mean VA in the anti-VEGF groups was better than the laser groups at six months (MD 9.63 letters, 95% CI 7.23 to 12.03; 3 studies, 473 participants; moderate-certainty evidence). There was a greater reduction in CRT in the anti-VEGF group compared with the laser group at six months (MD -147.47 microns, 95% CI -200.19 to -94.75; 2 studies, 201 participants; moderate-certainty evidence). There was only very low-certainty evidence on adverse events. There were no reports of endophthalmitis. QoL outcomes were not reported. Four studies compared anti-VEGF with intravitreal steroid (875 participants). The proportion of eyes gaining 15 or more ETDRS letters was greater in the anti-VEGF group at six months (RR 1.67, 95% CI 1.33 to 2.10; 2 studies, 330 participants; high-certainty evidence) and 12 months (RR 1.76, 95% CI 1.36 to 2.28; 1 study, 307 participants; high-certainty evidence). Mean VA was better in the anti-VEGF group at six months (MD 8.22 letters, 95% CI 5.69 to 10.76; 2 studies, 330 participants; high-certainty evidence) and 12 months (MD 9.15 letters, 95% CI 6.32 to 11.97; 2 studies, 343 participants; high-certainty evidence). Mean CRT also showed a greater reduction in the anti-VEGF arm at 12 months compared with intravitreal steroid (MD -26.92 microns, 95% CI -65.88 to 12.04; 2 studies, 343 participants; moderate-certainty evidence). People receiving anti-VEGF showed a greater improvement in QoL at 12 months compared to those receiving steroid (MD 3.10, 95% CI 0.22 to 5.98; 1 study, 307 participants; moderate-certainty evidence). Moderate-certainty evidence suggested increased risk of cataract and raised IOP with steroids. There was only very low-certainty evidence on APTC events. No cases of endophthalmitis were observed. AUTHORS' CONCLUSIONS The available RCT evidence suggests that treatment of MO secondary to BRVO with anti-VEGF improves visual and anatomical outcomes at six and 12 months.

Abstract
Retinal vein occlusion (RVO) is the second most common cause of vision loss from retinal vascular diseases in adults in the United States. Visual loss arises as a result of a host of factors, including macular ischemia and macular edema. Primary antivascular endothelial growth factor therapy is the current standard of care, with level I evidence demonstrating sustained visual gains up to 2 years after treatment in both branch and central RVO. Prompt antivascular endothelial growth factor therapy is important because delays in treatment yield lesser visual gains. Steroid therapy also improves visual outcomes in RVO but with higher rates of adverse effects, including cataract formation and ocular hypertension. Although the treatment burden can be high, these drugs have collectively revolutionized treatment outcomes in this disease state, providing improved visual outcomes over previous laser therapies.

Abstract
Retinal vein occlusion (RVO) is one of the most prevalent causes of visual loss in the Western World. Its pathogenesis is still not completely known. Chronic macular edema and ischemia compromise the functional and anatomical status of the retina. Antivascular endothelial growth factor (anti-VEGF) injections have demonstrated better results than other previous options, including observation or laser therapy. This narrative review aims to analyze the current aspects related to these drugs.

Abstract
This review assessed the real-world evidence of the management of macular oedema secondary to branch retinal vein occlusion (BRVO). A meta-analysis of 2530 eyes from 48 real-world studies of therapies for macular oedema secondary to BRVO was conducted. Baseline characteristics, visual, anatomical and safety outcomes were recorded. The weighted mean and weighted estimates from random-effects models were calculated for visual acuity (VA) and central subfield thickness (CST) changes at 6, 12 and 24 months. Primary outcome was change in VA (logMAR letters) at 12 months. Study quality was assessed using the quality appraisal checklist for case series developed by Institute of Health Economics. The mean baseline VA for the pooled data was 54.0 (51.5, 56.5) letters and the mean baseline CST was 501.3 (483.5, 519.1) µm. The random-effects estimate for mean (95% CI) change in VA was 14.6 (12.5, 16.7) letters at 12 months (n = 1727). The random-effects estimate for mean (95% CI) change in CST was -181.7 (-230.7, -132.7) µm at 12 months (n = 1325). The quality of studies varied considerably. Ocular and systemic adverse events were discussed in 79% and 42% of treatment arms respectively, with possible under-reporting. Visual and anatomical gains achieved in the real-world for anti-VEGF therapy were not as impressive as seminal RCTs, possibly due to reduced injection frequency in the real world and differences in baseline characteristics. There is an urgent need for consensus on the minimum efficacy, treatment burden and safety data to collect to strengthen the real-world evidence base.

Abstract
Locally administered steroids have a long history in ophthalmology for the treatment of inflammatory conditions. Anterior segment conditions tend to be treated with topical steroids whilst posterior segment conditions generally require periocular, intravitreal or systemic administration for penetration. Over recent decades, the clinical applications of periocular steroid delivery have expanded to a wide range of conditions including macular oedema from retino-vascular conditions. Formulations have been developed with the aim to provide practical, targeted, longer-term and more efficacious therapy whilst minimizing side effects. Herein, we provide a comprehensive overview of the types of periocular steroid delivery, their clinical applications in ophthalmology and their side effects.
